Corsair is a company that hardly requires an introduction; almost every PC user has heard of their name and a large number own at least one of their products. More advanced users know that Corsair is one of the oldest companies that's still around. The company was established in 1994 as a cache module manufacturer but their focus changed to DRAM modules a few years later.

Today we have the new Obsidian 450D case on our test bench; read on for the complete review.
